Efficiently controlling linear Gaussian quantum (LGQ) systems is a significant task in both the
study of fundamental quantum theory and the development of modern quantum technology …

Work within this thesis advances optimal control algorithms for application to magnetic
resonance systems. Specifically, presenting a quadratically convergent version of the …

The resonant absorption of light by an ensemble of absorbers decreases when the
resonance is inhomogeneously broadened. Recovering the lost absorption cross section is …

We propose an effective scheme to implement fast and robust population transfer with a
Josephson qutrit via shortcut to adiabaticity. Facilitated by the level-transition rule, a Λ …

We investigate the influence of nonlinear crystal's coupling modulation on wavelength
conversion based on Stark-chirped rapid adiabatic passage. The result shows that the …

In the field of nonlinear frequency conversion, the cascaded frequency conversion scheme
is an effective means to obtain new wavelengths. In this paper, we demonstrate efficient …

We demonstrate a highly efficient process of cascaded wavelength conversion among three
states that is based on the Stark-chirped rapid adiabatic passage technique, and enables …

We show that the technique of Stark-chirped rapid adiabatic passage (SCRAP), hitherto
used for complete population transfer among three states in atoms and molecules, offers a …

We propose a potentially practical scheme to realize arbitrary quantum state transfer
between two traveling atoms that go through a high-finesse cavity by using stimulated …

We propose a technique of a simultaneous excitation of disordered qubits providing an
effective suppression of inhomogeneous broadening in their spectral density. The technique …
